[jira] [Created] (AURORA-1959) Missing Ops prevent upgrade from 0.19 to master

Jordan Ly created AURORA-1959:
---------------------------------

             Summary: Missing Ops prevent upgrade from 0.19 to master
                 Key: AURORA-1959
                 URL: https://issues.apache.org/jira/browse/AURORA-1959
             Project: Aurora
          Issue Type: Bug
          Components: Scheduler
            Reporter: Jordan Ly
            Assignee: Jordan Ly


Ops removed between 0.19 and master causes issues when replaying logs. Because the Op no longer exists in the new version, the scheduler will throw an exception and fail during recovery.

The fix here is to deprecate operations over different versions. Do not write for one version and reads are no-ops. Then, you can remove the Op.
